Starbucks has not formally announced the product, but there have been sightings in the wild of a pink-and-blue-swirled drink called the Unicorn Frappuccino. From the descriptions, this resembles coffee in no way, shape, or form. It's a sweet/sour drink that is supposed to change flavor as you drink it, and from reports, the taste wavers between mango and Skittles. According to Eater, it should be unveiled on Wednesday. Mike Fahey at Kotaku drank one on Sunday and gives us a report.
It’s a cup full of coloring, sour and evil intent. I missed the mango initially due to the color and the somewhat apple-y sour tricking my taste buds into thinking I was drinking something else. Once the sour (mostly) faded, the Unicorn Frappuccino mainly made me wish I’d gotten a straight up mango one instead.

Snopes has some photographs of the ingredients shared by Starbucks employees at reddit, who seem to be as confused about the drink as the rest of us are.
